Leg-length inequality and low-back pain after Perthes' disease: a 28-47-year follow-up of 96 patients

J Spinal Disord. 1992 Dec;5(4):443-7. doi: 10.1097/00002517-199212000-00009.


A follow-up of 96 patients with Perthes' disease was made 28-47 years after onset of the disease. We paid special attention to leg-length inequality and its consequences and low-back disability. Leg-length inequality was a common finding, but low-back pain was not a significant problem. Leg-length inequality and lumbar scoliosis correlated poorly with low-back disorders. Degeneration of the lumbar spine was the only factor that correlated well with low-back pain.
